1
Just by logging, your impulse
buys quietly start to shrink.Once you notice your own patterns,
the brakes come on by themselves. -
2
Making the unconscious conscious
is the first step to change.See the habits and reasons you
couldn't before, and your choices change. -
3
You see what you could've bought instead —
so money returns not as a "lost past"
but as "future options."Turn regret into hope.
Your money is for your future.
Logging an impulse buy is
returning money to your future self.
Three steps. That's all.
It quietly piles up in the bowl.
No scolding.
You just see the running total.
“What could I have bought instead?”
One Switch game. Eight nice lunches.
The distance to your goal, shown gently.
Now on your phone.
Every time you log, a rainbow bubble drops in — falling into the bank and quietly collecting.
Why does this one stick?

Frequently asked
-
1 Do I really only log impulse buys?
Yes. Logging everything never lasts. Only log the moment you think “that was kind of a whim.”
Trust your gut, not a rulebook — that's the secret to keeping it up. -
2 Does it connect to my bank or credit card?
No. The meaning lives in the moment you write “this was a whim” by hand — not in automatic syncing. -
3 Which platforms are supported?
The iPhone app is available on the App Store, and the Android app on Google Play. -
4 Can I download it yet?
Yes. The iPhone app is live on the App Store, and the Android app on Google Play.
